I can hear you now.
Surprisingly easy to follow film about how sound travels, the importance of pitch and loudness etc etc. A real surprise, especially coming from an outfit such as EB films.

An unsound film
If you want to learn about sound, this film will not help. Poorly organized with lots of glossed-over jargon, poor explanations, and confusing illustrations. Tries get from the basic "what is sound?" to complex modal vibrations in a short educational film. A mess.
